Specification of Letters Patent.

Application filed February 23, 1912. Serial No. 680,755.

To all wiwm it may concern:

Be it known that I, FREDELLIA H. hi oynu, a citizen of the UnitedStates, residing at Akron, in the county of Summit and State of Ohio.have invented certain new and useful Improvements in Ring-TuningMachines. ot' which the following is a specification.

The side rings which engage the bead p01- tions of pneumatic tires onvehicle wheel rims to removably or detaehably maintain the tires inproper relation on their rims, are ordinarily made by rolling straightbars of the proper or desired cross-section. By machines proper lengthsof sueh bars are curved iuo annular or ring form. Then the abutting endsare welded together to torm a continuous ring. Subsequently the ring isplaced upon a sizing machine, which stretches it slightly, it necessary.to give. it the proper circular shape and the required diameter. But inpassing through these various operations. the (ross-seetion'of the ringis likely to become slightly distorted and the object of the presentinvention is to provide a mechanism of simple and eeonom ieal characterwhich will true up such sections so that the} will meet the rigidrequirements of the trade.

In order that those skilled in the art may have a -full and complete.understanding of this invention. I have illustrated a. preferred anddesirable embodiment of the same in the areompairving drawings forming apart of this specification. should be had in connectionwith thefollowing detailed description.

In these drmvings:

Figure 1 is a plan view of the machine;

Fig. 2 is a central vertical longitudinal seetion;

Fig. 3 is a. vertical crosssection 011 line 3-3 of Fig. 2;

Fig. l illustrates in section the details of construction of themechanism for adjusting one of the. bearings;

Fig. shows the manner in which the two rolls eoaet with the ring, and

Fig. (3 is an enlarged cross-section through the ring.

Referring to the d rawings, it will be noticed that the machinecomprises a mainframe to the top of which is bolted at 11, 11, the pairof standards 12 and 13, Which have provided in their lower portionsbearings 14: and 15 for the accommodationof the lower roll shaft 16'which at one end carries the -ot' the earingdrlork 25.

and to which reference upthe proper heads and G5 nuts. Each standardrecessed at l)ttll.'ll'lf;' .25; to

slidably aeconmualate a upper roll shat't 2e. and in order bearings maybe simultaneousljv dependently vertically adjusted 1., position theupper roll :2? earrieti ol' shal't Jt'v. with relation to t lh.- i actedupon. l supply in the.

. ot' the standards a threaded 37'' through \\liirher\'lemls ase1'e'\\'-tii"eu shaft 2* having an enlargement at i i end 2! reeeivedin a similarly shaped ma The upper and. of the serew 2b is made squareat 30. and just below sueh angular seetion there is keyed to 80 each ofthe serews in a sprocket wl gel 31. a. filfl'm'lx'tt chain 32 passingaround and eoacting with the pair of sprocket wheels. it is desired tovertically adjust one of t bearingblocks independently of the other. it,is merely neeessarv to ten'iporarily remove the sproeket chain 32 andapply handle 32-3 to the top ol the screw and turn it until the requiredadjustment is secured.

ln ease it is neeessanv to vertically adjust both of the beai-mgdiloekstogether, then the chain 32 is permitted to remain in its cooperativerelation with the. two Sp1fit-:0t wheels and by turning the handle 33when applied to either of the screws 28, then. as 05 will be readilyunderstood, both hearing blocks rise or fall equal amounts, the adjustment depending upon the extent of turning of the handle.

Each of the shal'ts 1(3 and 96, between its pair of bearings. isequipped with ball.- bearing 354 between eaeh pair of nuts 35 and Elliand the end of eaeh adjacent bean ing, those portions of the shaftaccommodatin the nuts bein screw-threaded s0 that by turning the nutsproperly the po sition of the shafts 1(3 and 26 may he shi i and therolls 17 and 97 eorrespondin moved. Each nut 35 is. of course, the. mainadjusting nut, the similar companion nut- 3 36 being the lock nut.

In order to drive the upper shaft 26 from shaft referred to, 1 key toshaft 16 a gear fit hinge-bolts 52, 52,

37, the teeth of which IZlGSll with those of a similar rear 38 on theback shaft 39. Rockingly mounted on this shaft 39 are a pair of links l0and also mounted on the shaft 26 are a pair of linlcs a l. The upperback shaft passes through apertures in all four of these links acting asthe hinge pin for such links. On shaft. I mount an intermediate gear l?)th teeth oi which inc-sh with gear -1 and a with gear l-l fixed to theupper roll sha 26, and by this 1' n of genre. the power from the lowershat; ll is transmitted to the upper shaft '25 re ardiess of thevertical adjustu'lcnt of the latter shaft, the rocking links at alltimes maintaining the various gears in proper association.

lit one end of the frame l 0, by means of a pair of bolts 45, :5, l.adjustably fasten the slotted support 46, thebolts passing through thevertical slot 4-? of the support a s is clearly indicated in Fig. 2. Atits lower end, support it? has an outstanding projection 48 hearing,against the bottom face of which is an adjustinq' screw 49 passingthrough a threaded aperture in a boss 5 projecting outwardly from theframe 10, as is clearly shown. should be clear,

therefore, that by loosening the nuts 45 and I turning; the adjustingscrew ill, any desirable vertical adjustment otthe support can bereadily and quickly secured. This support 46 51, 51, to which are hingedby means of the spaced arms 5 5, of a skeleton table cm ying threerollers 55, ms and 57 act a1 ed to overhang and proper y position therim side ring 58 which in cros. section is of the substantiallyhookshcped form ilhistrated in Fig. 6. One or more of these rollers maybe adjustable so as to more accurately position a ring and accommodaterings different diameters. in the present form oi the device I haveshown the table 5% slotted at 59 to permit adjustment of the rolle 56,it being under stood, as is-clcarly shown in Fig. that each of theserollers is'rotatably mounted on a bushing 66 on a bolt- 61, wherebyadjustment of the roller toward and from the center of the table may beeasily attained. Each roller has a flanged upper portion 62'v1hichoverlics the ring 58 to maintain the latter in its proper planeand prevent distortim of any art thereof. Near its center, table 54 haspivoted thereto at 63 a nut 64- passing through which is ascrew-threaded rod 65 having fixed thereto,

near its central portion, an operating handlefifi, the lower end of thescrew )assin l t:

has at its top two upstanding ears nut 67 suitably mounted on a bracket(58 port 46.

From this description and illustration it should be plain that the upperroll 27 is adjustable up and down from and toward the Work and may alsobe canted slightly to properly conform to the hook cross section of thering. Furthermore, the table 5% carrying the ring is adjustablevertically by means of the screw 49, and angularly by the screw 65, sothat the ring placed upon the table may be brought into properassociation with the ctr-acting rolls 17 and 27 which, during,theirrotation, true the ring and cause it to rotate on the table so thatthe entire circumference of the ring is properly trued and shaped, theserolls, as will be evident," constituting the driving means for revolvingthe ring during the truing action. Before beginning operations, thetable is so adjusted with relation to the rolls that the latter have notendency to bend the ring out of its true plane which is maintained bythe table and the antifriction rollers 55, 56 and 57.

While I have-herein indicated my invention as capable of embodiment in amachine for truing side rings of detachable vehicle rims. it is to beunderstood that the invention is not limited to machines employed forthis purpose, since the invention is susceptible of uses in a variety ofrelations. liurthermore. many minor mechanical changes may beincorporated in the machine illustrated and described herein withoutdeparture from the substance and essence of the invention, and Withoutthe sacrifice of any of its substantial benefits and advantages.

I claim:
